Don't let dicts spoil your code
I restricted the use of dicts in my code to make it easier to follow and maintain. Here's my explanation of the benefits and advice on what you can use instead. Bonus point: what to do with all the legacy code when there's no time to eradicate all the dicts.

I'm not a fan of strlcpy(3)
strlcpy(3) is an OpenBSD function which is often hailed as a safer replacement for strcpy(3) and/or strncpy(3) . One of the obvious issues with strlcpy is that it's not safe if src isn't null-terminated. However, that's not the reason I don't like strlcpy. In fact despite knowing this, I used to think it was an okay…

Beating the Compiler
In modern times, everyone knows that writing assembly is a fool's errand: compilers are the result of literal engineer-centuries of work, and they know the processor much better than you do.

The search for easier safe systems programming
I've been involved in the Rust project in some form or another since 2016, and it's a language I'm very comfortable using. Many Rust programmers could say the same . But, if we take a step back and are honest with ourselves, we'd admit that the road to getting to that level of comfort was difficult.

Implementing Natural Conversational Agents with Elixir
In my last post , I discussed some work I had done building Nero, the assistant of the future that I’ve always wanted. I ended up creating an end-to-end example which used Nx, OpenAI APIs, and ElevenLabs to create an in-browser home automation assistant. For a first product, it’s decent. Nero is a neat little party…

Stacking triangles for fun and profit
One thing you may have noticed about the trigonometric functions sine and cosine is that they seem to have no agreed upon definition. Or rather, different authors choose different definitions as the starting point, mainly based on convenience. This isn’t problematic or even particularly unusual in mathematics: as long…
